Need help in installation

Hey I install discourse and follow advance developer guide But I am getting this error

I’ve removed the unsupported-install tag as it seemed it was added in error, though I’m not sure how you’ve generated this error from a dev install?

This happens to me also when trying to run discourse without ember-cli:

Hm. This happens when visiting http://localhost:3000/.

In my case, discourse is running fine on http://localhost:4200/ nevertheless.
